Our definition of interdisciplinary thinking includes a combination of approaches that most closely follows “fusion” methodology (of course, that’s why we call our elders by this title!). Fusion is an interdisciplinary approach that merges integrated content across subject areas with broader skills, knowledge, and dispositions for real world action, responsibility, and accountability. Our definition should not be confused with  multidisciplinary learning. Service learning and a transdisciplinary approach allow further integration across class sessions with an emphasis in project-based learning and students being a part of the negotiated curriculum process. At Vector, we use thematic collaborative planning to hold these schoolwide units together and offer cohesion to our entire shared community.
